Application filed May 5, 1913. Serial No. 765,510.

To all whom t may concern Be it known that l', WILLIAM BREWER, a citizen of the United States, and a resident of the city of Pittsburgh, in the county of Allegheny and' State of Pennsylvania., have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

This invention relates to car. roofs, and more particularly to outside metal roofs comprising movably mounted transversely extending sheets whose side marginal portions are connected by flexible or loose waterproof seams. r

It has for its principal objects to provide improved means for securing the end sheets so that the sheets are retained throughout their length; to allow for a limited movement of the end sheets and yet prevent leakage under them; and to attain certain advantages which will hereinafter more fully appear.

The invention consists in securing the end sheets continuously along the end of the car'; and it further consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure l is a top plan View of the end portion of a car roof illustrating an embodiment of the invention; Fig. 2 is an end elevation; Fig. 3 is a vertical section on the line 3-3 of Fig. 2 on an enlarged scale; Fig. 4 is a vertical section on the line 4 4 of Fig. 2; and Fig. 5 is a vertical section on the line 5 5 of Fig. 2.

The roof shown in the drawing is of the radial type. That is',I the root is arched or curved on a radius. The metal sheets l, of which only an end sheet is shown, extend continuously across the car from eaves to eaves. The ends of the sheets may be .turned down over the eaves, or they may be otherwise suitably arranged and secured in any desired manner. The outer side marginal 'portion of the end sheet is turned downeyepthe end of the car, as at 2, into a continuous recess or rabbet 3 fascia or molding 4.

The roof'substructure shown in the drawing is of the type known as the 4 all metal in the end type. That is, the purlins and carlines or i the longitudinal and transverse frame members are oi metal. In the drawing, only the purlins 5 are shown. These purlins are supported at' their ends on the end plate 6; the ends of the purlins being turned down over the outside of the end plate and secured thereto by bolts 7 An elongated retaining cap 8 of angle section, and preferably made of sheet metal, is secured to the end fascia 4, below the rab? bet 3, at intervals throughout its length by bolts 9 which extend entirely through the end plate 6. The cap is also secured at points between the bolts 9 by nails 10 which are preferably driven. into the end plate. Preferably, the cap 8 is made in one piece and extends from side to Side ot the car, but in some cases, if desirable, the cap may be made in two or more sections whose meeting ends may be made to abut or overlap. The margin or' the portion 8a of the end cap, which overlaps the roof sheet, is preferably bent back or hemmed, as at 8b, so as to reinforce and stiften the end cap along the overlapping edge.

ln practice, the overlapping portion 8a of the cap is made to lie close to the roof sheet so as to prevent the Sheet from lifting, but with sufficient looseness to permit the sheet to move lengtllnvise and sidewise; a'nd in order to prevent an accumulation of cinders or any other substance that might be forced between the cap and roof sheet into the rabbeted portion 3 of the fascia 4, and also to provide the proper drainage for any Water which may get under the cap, the downturned portion of the cap is corrugated or crimped vertically at intervals throughout the length of the cap7 as at 11. Preferably,

these corrugations are flared or widened toward the bottom edge of the downturned portion of the cap to further prevent clogging. These corruga'tions l1 also serve to Stillen the cap. The retaining cap, in addition to holding down the roof sheet, also serves as a tie-plate and Stiifening element for the end oln the car in the region of the root, particularly in cases Where the cap extends continuously from side to side of the car.

Obviously, the structure admits of con-v siderable modification without departing iiroin the invention., Therefore,

' wish to be limited to the specific ccnstrncA1 tion and a vertical ange portion, rthe vertical portion of said strip being corrugated vertically, whereby it is vertically flexible.

2. ln a curved car roof, vthe combination with an end sheet, of an upwardly curved flexible flashing strip' and retaining member conformable to the-curve of the roof, said flashing strip consisting of al vertical flange portion'fastened to the end of the car below the eaves and a horizontal Harige portion overlapping the adjacent marginal portion of the end sheet, the vertical ila-nge portion of said flashing and retaining member being corrugated vertically, the corrugations being widened toward the bottom edge of the ange portion, whereby said iashing and retaining member is exible in a vertical plane and substances may readily escape from under it.

3. In a car roof, the combination with an end sheet, the marginal portion of said end sheet, beingturned down over the end the car, of an end flashing strip and i-etaining member comprising an angle shape sheet metal cap having one flange corrugated vertically and Jfastened tothe end oE the car.

y between the corrugations and having the other ange smooth and overhanging said end sheet, whereby said end sheet is retained at' the end of the oar, said corrugations stili'ening said iiange to retain said end sheet and making said cap enible between its ends.

4. ln a ear roof, the combination with an end sheet, the'inarginal portion of said end sheet being turned down over the end of the car, ofl an end flashing strip and retaining member comprising an angle shape sheet metal cap. having one flange turned down and fastened to the end of the car and hav ing its other flange horizontally' disposed over end sheet, Asheet is inovably secured at the end the car, the downtiirned llange ci said cap being corru-v gated vertically, the corrng'ations being widened toward 'the bottoni edge of said downtiirned portion, whereby said cap can- .be bent on its longitudinal anis in a vertical direction.

5. lin a curved arched car roof, the combination with an end sheet extending continuously across .the car from eaves to eaves, of a continuons angle shape retaining member one ory whose ianges is secured along the end of the car, the other ange being disposed inwardly so as to overhang the end sheet, said retaining member being corrii gated transversely whereby it is flexible to conform to the curvature of the roof.

6. in a curved arched car roof, the combination with an end sheet extending continuously across the car from eaves to eaves, the end of the car having a continuous rabbet into which the side marginal portion is turned down, oli a continuous angle shape retaining member one of whose flanges is se cured along the end of the car below said rabbet, the other flange being disposed in- Awardly so as to overhang the end sheet, said lirst mentioned flange being provided with vertical coirugationsspaced from `the end of 'the car 'whereby said. retaining member is flexible to conform to the curvature of the and substances can escape from under it. i

7. An angle shape retaining strip for the eaves end of a curved car roof, said strip comprising a vertical flange having tapering vertical corrugations increasing in size toward the bottom whereby said flange is 'vertically flexible and the escape of cinders from thereunder is facilitated.
